EKWB could be making a compatible block. I adapted the corsair 6800/6900 reference waterblock to fit. Remove the metal shroud, shave the acrylic so the two longer capacitors fit, then the holes line up perfectly to fit tight to the board, with great contact. I connected the in/out tubing to the underside, as the PCB covers the upper side.
Both the temps and noise are now amazing, running just shy of 2700 on the core, barely a whisper from my rig!
